Abstract
In order to replace fossil fuels and to reduce CO2-emissions, the use of thermal solar energy with common long-term storage of the heat is one of the most promising possibilities. These installations require a common storage tank that is able to provide warm water for a long period into the local district heating network. They may, depending on their dimension, provide as much as 50 to 70 % of the annual heating needs of a residential quarter. In addition to this, these systems can use innovative techniques, for example concerning their connection or feeding into a heat network and offer large energy saving potentials in comparison with single installations. In Ballerup, a municipality close to Copenhagen, solar district heating is covering parts of the heat demand in a living area with 100 apartments. This, combined with other initiatives, has caused a remarkable decrease in the heat bill paid by the tenants. The project inspired a large number of similar projects with global, low energy, building designs, both in Denmark and in other European countries.
